Dolphins Williams, Steelers Polamalu questionable

The Dolphins could be without RB Ricky Williams (shoulder) this Sunday when they take on the Steelers.

After fully practicing one day early in the week, Williams was limited for the second consecutive day Friday, leaving his status for the game as questionable. Dolphins coach Tony Sparano said he feels comfortable with second-year RB Lex Hilliard and his ability to handle a heavier load if he’s called upon to do so.

The Steelers, meanwhile, listed S Troy Polamalu (knee) as questionable after he was limited in practice all week. Polamalu missed the previous six games because of his injury.

The Steelers (8-7) and Dolphins (7-8) both need to win this game, then receive help, to make the playoffs.
